YACK Operation Manual
Version MY181210
L - ULTIMATIC MODE
Sets the keyer into ULTIMATIC mode. In Ultimatic mode always the last paddle to
be touched is repeated indefinitely when paddles are squeezed
X - PADDLE SWAP
DIT and DAH paddles are swapped.
F - FARNSWORTH PAUSE
Allows setting of an extended inter-character pause in all playback modes which
makes fast keying easier to understand. Note that this of course only influences RECEPTION, not
TRANSMISSION. If you desire Farnsworth mode in transmission, please manually pause during characters.
COMMANDS – TRANSMITTING AND TONE
I - TX INVERT
This function toggles whether the "active" level on the keyer output is positive or negative.
This setting is dependent on any additional attached keying circuits or radios. Normally this command is left
alone.
K - TX DISABLE
Toggles the setting of the TX keyer output. In default state the keyer switches the transmit
line when it is in keyer mode. Toggling this setting enables or disables that function. NOTE: Keying is always
off in Command mode.
S - -SIDETONE
The side tone oscillator setting is toggled (ON -> OFF or OFF -> ON). NOTE: This setting is
only of relevance for regular keying mode. Side tone is always on in command mode.
COMMANDS – FEATURES
C - CALLSIGN TRAINER
The keyer plays a generated 2x2 call signs (side tone only) at the current WPM
setting. The call signs are then entered back using the iambic key. If it is repeated correctly, "R" is played and
the next call sign is given. If a mistake was sensed, the error pro-sign (8 dots) is sounded and the current call
sign is repeated again for the user to try once more. If nothing is keyed for 10 seconds, the keyer returns to
command mode.
Z - ADVANCED TRAINER
Similar to the training mode above except on each successful entry the speed is
increased by 1WPM. An unsuccessful entry reduces the speed by 1WPM. Pressing the command button will
terminate the training, return the keyer to the original WPM speed, and give statistics of speed at end of session,
number of calls sent, and number of calls correct. Do not press command mode while the keyer is sending. The
last call sign sent is not counted.
N - BEACON MODE
The keyer responds with "N" after which a number between 0 and 9999 can be keyed.
After a 5 second timeout the keyer responds by repeating the number and 'R'. Once the keyer returns to keyer
mode, the content of message buffer 2 is repeated in intervals of the message length plus N seconds. The setting
is preserved in EEPROM so the chip can be used as a fox hunt keyer. Returning to command mode and entering
an interval of 0 (or none at all) stops beacon mode. Keyer will respond with 'R'.
Y - FOXHUNT MODE
When toggling this command the transmitter output will stay keyed down the entire
time a memory is played. Toggling again will resume the memories back into on-off-on keying mode. This
command works along with the Beacon command to allow a setup, such as an FM transmitter, to be used as a
beacon or fox hunting box.
